" jquery.jsonp.js" GET工作. POST PUT DELETE OPTIONS怎么样? [英] "jquery.jsonp.js" GET works. What about POST PUT DELETE OPTIONS?

问题描述

除了GET(POST，PUT，OPTIONS，DELETE)之外的jsonp http方法

使用jquery内置的$ .ajax方法看起来像这样

$(document).ready(function() {
    $.ajax({
    type: "GET",
    url: "http://myurl.com/webservice&callback=?",
    ...
});

只想引起注意type: "GET",行 使用$ .ajax执行http PUT只需更改type: "PUT",

此代码示例来自使用jquery ajax从跨域进行JSON解析

不使用$ .ajax

使用Google代码的jquery.jsonp https://github.com/jaubourg/jquery-jsonp

这是将jQuery方法与jQuery方法结合使用的示例

$.jsonp({
    cache: false,
    url: 'http://www.mydomain.com/logicalurl/2/',
    callbackParameter: 'callback',
    timeout: 10000,
    success: function(json, textStatus, xOptions) {
        myglob = json;
        MyModulePatternObject.initNew(json);
    },
    error: function (xOptions, textStatus) {
    console.log("fail");
    }
});

这很好用.不是我的问题，如何执行GET jsonp请求.

在$ .jsonp中，想要执行其他http方法:PUT POST DELETE OPTIONS ...? $ .jsonp是否支持type="PUT",?

在文档中完全没有提到它:API.md和TipsAndTricks.md在源代码中也没有.

更新

@ohgodwhy 有一个hack(iframe/代理)可让POST 2跨域工作. 通过JSONP和jQuery使用PUT/POST/DELETE

@thefrontender 链接的文章建议调查跨源资源共享(CORS)"

浏览器

CORS支持 http://caniuse.com/cors

同一篇文章还说:您可以将JSON编码为URL参数，但即使想到了也感到羞耻."在整个历史上，羞耻从未阻止任何人?简单，懒惰，并且在有限的情况下可以完成工作.

谢谢4个人...

解决方案

JSON-P的工作原理是将脚本标签注入文档中:这不是传统的XHR请求.

因此，您通常只能执行GET请求.您无法执行PUT请求.

本文中的更多详细信息: http ://johnnywey.wordpress.com/2012/05/20/jsonp-how-does-it-work/

jsonp http methods besides GET (POST, PUT, OPTIONS, DELETE)

Using jquery built-in $.ajax method looks like this

$(document).ready(function() {
    $.ajax({
    type: "GET",
    url: "http://myurl.com/webservice&callback=?",
    ...
});

Only want to draw attention to the line type: "GET", With $.ajax performing a http PUT would be simply change type: "PUT",

This code example comes from JSON parsing from cross domain using jquery ajax

Not using $.ajax

Using google-code's jquery.jsonp https://github.com/jaubourg/jquery-jsonp

Here is an example of using jquery.jsonp.js with the GET method

$.jsonp({
    cache: false,
    url: 'http://www.mydomain.com/logicalurl/2/',
    callbackParameter: 'callback',
    timeout: 10000,
    success: function(json, textStatus, xOptions) {
        myglob = json;
        MyModulePatternObject.initNew(json);
    },
    error: function (xOptions, textStatus) {
    console.log("fail");
    }
});

This works perfectly. How to do a GET jsonp request is not my question.

In $.jsonp, would like to perform the other http methods: PUT POST DELETE OPTIONS ... ? Does $.jsonp support the type="PUT",?

It's not mentioned at all in the docs: API.md and TipsAndTricks.md Nor in the source code.

UPDATE

@ohgodwhy There is a hack (iframes / Proxy) to get POST 2 work cross domains. Using PUT/POST/DELETE with JSONP and jQuery

@thefrontender Linked article suggests looking into, "Cross-Origin Resource Sharing (CORS)"

CORS support by browser http://caniuse.com/cors

Same article also says, "You could encode JSON as a URL parameter, but shame on you for even thinking that." In all of history, shame never stopped anyone? Simple, lazy, and in limited cases gets the job done.

Thx 4 everyones help ...

解决方案

JSON-P works by injecting a script tag into your document: it is not a traditional XHR request.

So you can usually only perform GET requests. You can NOT perform PUT requests.
